DRINK-MIXER.

Specification of Letters Patent.

Patented Apr. 1, 1919.

Application filed February 28, 1918. Serial No. 219,677

To all whom it may concern:

Be it known-that I, CURTIS W. Comm,-

a citizen of the United States, residing at Holly, in the county of Prowers and State of Colorado, have invented certain new and useful Improvements in Drink-Mixers, of which the following is a specification.

This invention. relates to agitation, and more especially it is a device for stirring. the contents of'a glass while being drawn from a faucet, such as a fancy drink served at the soda fountain.

The object of the invention is to provide the faucet with a stirrer standing adjacent and a little below the nozzle of the faucet and up over which the glass is passed in the act of bringing it in position under said nozzle, and driving the stirrer by a motor whose action is controlled by the movement of the faucet handle, or driving the stirrer directly by the movement of the handle itself.

These objects are carried out in the manner described below, found in the claims, and shown in the attached drawings, where- 1n Figure 1 is a side elevation illustrating one form of my invention, and

Fig. 2 is a front elevation of a faucet with another form of my invention applied.

Fig. 3 is a front elevation showing diagrammatically the wiring to the motor and the switch in said wiring.

In the drawings herewith I have used the letter G to indicate an ordinary glass such as is employed at soda fountains. F is the faucet, usually having a globular head H v and a pendant nozzle N, and the valve within the head of this faucet is actuated by a handle which inthe present case is shown as composed of a yoke Y having a knob K at its top. No novelty is claimed for the parts thus far described.

The agitator forming part of this inven tion may be said to consist of the stirrer which in the present instance is a number of blades or wings 1 mounted on an upright shaft 2 which latter is journaled in appropriate bearings 3 carried by the nozzle as best seen in Fig. 2. The stirrer stands at a point near and subjacent to the nozzle, so that when the glass G is brought up under such nozzle to a point where the latter will deliver into it, it is automatically passed upward over the stirrer as shown in Figs. 1 and 2. Thereafter while liquid is being drawn into the glass, means are employed to rotate the stirrer so as to agitate'the contents, or in other words to mix the drink being prepared. The driving mechanism is shown in two forms, respectively illustrated in Figs. 1 and 2.

In Fig. l the number 5 designates a small electric motor connected with the upper end of the shaft 2 and driven by a current of electricity led from a suitable source along Wires 6. This motor may be carried on the exterior or the interior of the head A of the faucet, but it is important that the control switch 7 shall stand in position to be actuated by themovement of the yoke Y. That is to say, as shown in Fig. 1, when the yoke Y of the handle moves forward or to the left in the act of opening the faucet, it moves in contact with the switch 7, diagrammatically shown as a sliding pin in Fig. 3, and closes the circuit along the wires 6 to the motor 5, and rotation of the latter drives the agitator in a manner which will be clear; whereas on return of the handle to an upright position as shown, pressure is automatically removed from the switch 7 which opens and cuts off the current and stops the rotation of the motor.

In F ig. 2 mechanical means are shown for driving the upright shaft 2. Here the latter has a bevel pinion 8 on its upper end meshing with a bevel gear 9 which is fast on one arm of the yoke Y, and therefore as the handle is swung forward the comparatively large gear rotates the comparatively small pinion for a number of revolutions in one direction so as to actuate the agitator, and when the handle is returned to its normal position the stirrer is actuated in the opposite direction. I do not wish to be limited to any specific form of agitator or stirrer blades 1, nor to their exact number and disposition.

The drivingmechanism illustrated in Fig. 1'

is set in motion by the movements of the handle but actuated from its own independent source of power. The driving mechanism illustrated in Fig. 2 is both actuated and driven by the movements of the handle. But in both cases or in fact in any case the driving mechanism is controlled by the movements of the handle, because such is the gist of my invention.

What is claimed as new is 1. In a drink mixer, the combination with a faucet having a handle, and a shaft carried by said faucet and having a stirrer disposed near and subjacent to the faucet-nozzle; of means for controlling the action of said shaft by the movementsofsaid handle.

2. In a drink mixer, the combination with a faucet having a handle, and a rotary shaft carried by said faucet and having a stirrer disposed near and subj acent to the faucetnoZzle; of driving mechanismfor said shaft controlled automatically by the opening and closing movements of said handle.

3, 'In a drink' miXer,the combination with a faucet having a handle,"and'a rotary shaft carried. by said faucet and having a stirrer disposed near and subjac'ent to the faucet: nozzle; of driving mechanism for said shaft, means for supplying energy to said mechanism from a remote source, and means for automatically controlling the supply of such,

- energy by the movements ofsaid handle.

I 4'. In a drink mixer, the combination with a faucet having a handle, and a rotary shaft carried by. said faucet and having a stirrer.

Copies of thispatent may be obtained for disposed near and subjacent to the faucetnozzle; of a motor for driving said shaft, themotor beingcarried by the faucet, means for supplying energy to said motor, and switch mechanism for applying or cutting offsaid energy automatically by the movements of the faucet-handle to open position and back to closed position.

' 5. In a drink mixer, the combination with a faucet having a swinginghandle, and a stirrer mounted on an upright shaft; :of; an electric motor mounted on said faucet and connected to said shaft,wiresleading to, said motor, and a circuit closer controllingsaid wires and disposed to be actuated bythQ movements of the faucet-handle,

In testimony whereof Iaffix my signature in, presence of two witnesses.
